bonding: remove __get_next_port()

Currently this function is only used in constructs like

for (port = __get_first_port(bond); port; port = __get_next_port(port))

which is basicly the same as

bond_for_each_slave(bond, slave, iter) {
	port = &(SLAVE_AD_INFO(slave).port);

but a more time consuming.

Remove the function and convert the users to bond_for_each_slave().
